Abstract:
Semiconductor carbon nanotubes functionalized by hydrogen and a method for fabricating the same, wherein the functional hydrogenated semiconductor carbon nanotubes have chemical bonds between carbon and hydrogen atoms. The semiconductor carbon nanotube fabricating method includes heating carbon nanotubes in a vacuum, dissociating hydrogen molecules in hydrogen gas into hydrogen atoms, and exposing the carbon nanotubes to the hydrogen gas to form chemical bonds between carbon atoms of the carbon nanotubes and the hydrogen atoms. The conversion of metallic carbon nanotubes into semiconductor nanotubes and of semiconductor nanotubes having a relatively narrow energy bandgap into semiconductor nanotubes having a relative wide energy bandgap can be achieved using the method. The functional hydrogenated semiconductor carbon nanotubes may be applied and used in, for example, electronic devices, optoelectronic devices, and energy storage.
